Is the feedback amplifier circuit a closed loop circuit?
In an amplifier circuit, a circuit with feedback was called a closed-loop circuit. The feedback amplifier circuit had a feedback path from the output to the input. This feedback circuit was in a closed-loop state, so the feedback amplifier circuit was a closed-loop circuit.

The difference between one-way circuit and three-phase circuit
A one-way circuit had only one line and one neutral line. The current flowed from the line to the neutral line. For example, many electrical appliances in our home use a one-way circuit, such as lights and televisions. It is relatively simple, and the voltage is usually 220V.
In a three-phase circuit, there were three live wires and sometimes a neutral wire. The voltage between the three wires was 380V. This kind of circuit was commonly used in the industry. For example, some large-scale electric machines used three-phase circuits. The three-phase circuit could provide more power than the one-way circuit, and it was more efficient.

Which is better, a one-way circuit or a three-phase circuit
One-way circuits and three-phase circuits had their own characteristics and were suitable for different scenarios. It was not easy to determine which one was better.
From the perspective of transmission cost and non-metallic consumption, under the same transmission power, distance, voltage, and line loss, three-phase transmission lines can save a lot of transmission costs and non-metallic metals. The amount of copper used is about 3/4 of that of single-phase transmission lines.
In terms of generators, three-phase alternators were smaller, lighter, and cheaper than single-phase alternators of the same capacity. A three-phase transformer was not only more economical than a single-phase transformer, but it also had two types of output voltage. It could be connected to either a three-phase load or a single-phase load.
For the motor, the three-phase motor was simpler in structure than the single-phase motor of the same capacity. It was reliable, cheap, had good performance, stable operation, and high efficiency. Three-phase power sources were easier to generate rotating magnetic fields and were suitable for powering three-phase electric machines, while single-phase circuits were relatively inferior in this regard.
However, in daily life scenarios, such as household electricity, a single-phase circuit could meet the electricity needs of electric appliances such as lights, computers, electric kettles, fridges, and 1P air conditioning. Because the power of these appliances was relatively small, 220V single-phase alternating current could be used. In the industry, due to the large power of the equipment, the need for a stable rotating magnetic field, and for economic considerations, most of them used three-phase electricity.

Is the circuit fiction or nonfiction?
It's hard to say for sure whether the circuit is fiction or nonfiction without more details. If it's described with scientific accuracy and relates to real-world electronics, it's nonfiction. If it has elements of fantasy or imagination, it might be fiction.

Eulerian Circuit of a Digraph
The Eulerian circuit of a directed graph was defined as a circuit that passed through each edge of the graph once and only once and traveled through each apex of the graph (the apex could be multiple times).
A strongly connected graph G has an Eulerian circuit if and only if the in-degree of each node is equal to the out-degree. The proof was as follows:
- “⇒”： If a strongly connected graph G has an Eulerian circuit, for the starting point s, suppose that there are x times from s, and to return to s, it must return to s exactly x times, so the in-degree and out-degree of the starting point s must be equal; For a non-starting point v, if the out-degree y is greater than the in-degree x, it cannot return to v after the xth time, and the remaining y-x exit edges cannot be accessed; If the out-degree y is less than the in-degree x, then it cannot be accessed after entering v for the y + 1 time. Therefore, the in-degree and out-degree of the non-starting point v are also equal. Therefore, when graph G has an Eulerian circuit, the in-degree of each node v is equal to the out-degree.
- "": Assuming that the degree of entry of each node in the directed strongly connected graph G is equal to the degree of exit, starting from the starting point s (each edge can only be traversed once, but the point can be traversed many times), it will eventually return to the starting point s. Because if we didn't return to the starting point in the end, there is a path s->v1->v2->... ->vi (vi is not equal to s). It can be seen that the number of times we enter vi is one more than the number of times we walk out of vi, so there must be at least one edge from vi that has not been visited, so it is not true. After traversing once, a sub-loop would be formed. On this sub-loop, a point s1 different from point s would continue to traverse, forming a sub-loop with s1 as the starting point (also known as the termination point). These two circuits had no common edges and could be combined into a loop, such as s->…->e->s1->f->…->s1->…->s. If it continued to expand, it would inevitably form an Eulerian loop.

The components of the feedback circuit are
The components that make up the feedback circuit are different for different types of feedback circuits and application scenarios. For example, in a voltage stabilizing feedback circuit, common components include a sensing resistance, TL431, an optical couplet, etc. In some circuits, a feedback circuit may be formed by components such as a resistance, a voltage amplifier, and a voltage amplifier. For example, from the output point to the negative input of the differential amplifier, there is a resistance connected in parallel with two resistances, and from the negative input to d, there is a resistance and a voltage amplifier. In addition, in the feedback circuit, the operational amplifier was the core component, and it formed a circuit to guide the feedback signal with external components such as a resistance or a amplifier.

What is a Flyback Circuit?
Flyback circuits were a common type of circuit in electronic circuits. To put it simply, it was like a little mage who had a unique ability in the conversion and transmission of electrical energy. In this circuit, when the primary coil of the transformer was energized, it was like a stingy person. It first stored the energy and stored it in its magnetic field. When the primary coil was powered off, it would release all the energy stored in it to the secondary coil, just like opening a small energy warehouse and pouring things out. This circuit was useful in many electronic devices, such as some power adapters. It was used to effectively convert and process electrical energy.
